Teaching children to be cooperative with other children is one of the hardest things a parent can do. Cooperation is more than just sharing with other children. Talking to your kids about their feelings and how to identify them will help in the future because the children will realize that talking and cooperating with others about your feelings is mentally healthy.
When your children are doing acts of care, reinforce that act and instill a good nature in them. Explaining the beginning and end of certain situations will help your child realize that cooperating will get things done.
One of the best ways to make sure your child is able to understand what caring is, is to talk to them about their feelings and to identify those feelings with them
When you see your child doing something good and caring, reinforce them. It will show them that when they do caring things, good results will happen
Explain to them certain situations where having a caring nature would be a good thing to have. Explaining volunteering, or even volunteering will greatly reinforce them.
